Interbrand ranked Hyundai 11th among the agency’s 50 Best Global Green Brands, a new global report by the agency. Hyundai placed fourth among the seven automotive brands that made the survey.

“The company is so confident in its fuel efficiency that starting this year it is reporting monthly fleet fuel efficiency figures in the U.S.,” Interbrand wrote in the survey. “Hyundai has recently seen strong improvements in energy, GHG emissions, water, waste, and toxic emissions.”

The survey, which questioned more than 10,000 respondents in 10 countries, examined each company’s environmental record and how the company is perceived by consumers. Companies were judged based on their performance, their environmental impact, their sustainable growth strategy and their corporate social responsibility programs.

Hyundai rolled out the Avante LPi hybrid in 2009 and the Sonata hybrid in 2011.

Hyundai plans to bring plug-in hybrid vehicles to market soon, while the company is currently operating test fleets of its hydrogen fuel-cell electric vehicles and pure-electric vehicles, called BlueOn.
